COMBINATION PADLOCK.

My invention relates tocertain improvements in combination locks,especially locks having elongated shackles, although certain parts ofthe invention can be applied to swivel shackles as well. i

In the type of lock having a long shackle, the casing is perforated forthe passage of the shackle therethrough. a

One object of the invention is to so design the mechanism that theshackle can be inserted freely at one end of the lock but cannot beinserted in the casing at the opposite end of the lock.

The invention further relates to certain improvements in thelocking-bolt forlocking the shackle to the casing, and also to theparticular stop mechanism used to prevent the entire withdrawal of ashackle in a lock of the sliding shackle type. 3

In the accompanying drawings:

Fig. 13 is a view illustrating the mechadetached perspective view ofnism as applied to a lock having a swivel shackle; and I 2 Fig. 14 is aView illustrating a modification of the means for preventing theinsertion of the shackle into the casing in the wrong direction. 1 isthe casing of a lock, which is cylindrical in the present instance andconsists of a back-plate 2 and an integral flange 3, which latter in thepresent instance is rolled over at 4 upon the cover-plate 5.-This'cover-plate has a lug 5 which enters a recess 3 in the body portionto prevent the cover plate from turning .on the casing. Other means offastening the cover-plate to the casing may be devised withoutdepartingfrom the essential features of the invention. W' thm the casingin: the present instance is a bottom plate 6, having a spindle 7 onwhich are mounted tumblers 8 and spacing washers 9. A coil-spring :10"on the spindle yieldingly holds the tumblers and washers in position. Aknob 11, mounted. in the casing, is secured to a notched disk 12, andthis disk actuates the tumblers. has a pointer 13, and on thecover-plate is a dial 14, clearly shown in Fig. 1. Mounted portion ofthe look. This springtends to yieldingly hold the bolt in lockedposition.

The shackle 20 is of the long-leg type, and both legs are notched sothat the shac le can be reversed in order that the nose18 may engageeither ot'the series of notches,

but it cannot be inserted into the look from' the bottom, as the end ofthe leg of the shackle will strike a stop 23, adapted to a slot 24 inacasing 25. One of thelegs of the shackle extends entirely through this"s PATENT OFFICE.

The knob casing as shown in Fig. 2. The stop 23 is beveled at 26, asshown in Figs. 5 and 11, to allow the shackle to be inserted through oneend of the lock casing. The stop 23 is held yieldingly in position by aspring 27, secured at 28 to the casing 25.

On the lower end of the bolt-carrying lever 15 is a projection 29, whichis engaged by an arm on a dog 31, which is pivotally mounted on a pin 32secured to the bottom plate 6. A spring 33 tends to force the portion3tof the dog against the edges of the "tumblers S, and when all of thesetumblers are moved to a certain position, all of the notches of thetumblers are in alignment, and the spring 33 will force the. portion 3stof the dog 31 into the notches and thus release the bolt-carrying leverfrom the control ofthedog, so that the lever will move the bolt to theposit-ion shown in Fig. 3, in order thativthe shackle can be withdrawn.

A stop-pin 35 limits the movement of the lever 15 in one direction,while the arm of the-dog limits it in the opposite direct-ion. Theupward movement of the bolt is limited bya stop 36 on the lever, thisstop in the present instance being boot from the lever as shown in Fig.7.

By the foregoing, it will be seen that the bolt will yield for theinsertion of the elongated. shackle to any position desired, and theshackle will be-loekedagainstwithdrawa'l until the'bolt is retracted asin Fig. 3. The stop 23 does not interfere with the longitudinal movementof the shackle when it is inserted in the right direction, but shouldthe shackle be inserted from the bottom, then the stop will interferewith the movement of the shackle and thus prevent the insertion of theshackle into the wrong end of the lock casing.

In Fig. 13 I have shown a. lock having a swivel shackle, and the longleg of the shackle in this instance has a shoulder 37 which is. engagedby the stop 23 and limits the longitudinal movement of the shackle, butallowsthe shackle to be turned freely in the casing when released fromthe locking mechanism.

In some instances, in place of using the stop illustrated in Fig. 11,the stop shown in Fig. 1% maybe used, which rests normally in the pathof the shackle, and which would prevent the insertion of the shackle atthe wrong. end ofthe casingbut allow the shackle to be freely insertedin the opposite end of the easing.

By mounting the lockingmechanism on the bottom plate, the mechanism canbe assembled complete and then inserted in the casing.

I claim:

1. The combination in a padlock, of a casing; 1 shackle adapted to thecasing; a pivotally mounted bolt-carrying lever; a bolt pivotallymounted thereon; a dog arranged to hold the bolt in the locked position;tumblers acting in conjunction with the dog; and means for actuating thetumblers to move them into locked or unlockeil position.

2. The combination of a casing having through openings; an elongatedshackle having two notched arms; a shackle casin secured to the lockcasing; a yielding stop extending into the opening of the raw so as toallow the insertion of the shackle into one end of the lock butn'eivcntiug the insertion of the shackle into. the opposite end of thelock; and locking meclmuism arranged to engage the other arm of theshackle.

3. Thecombination of a lock casing having through openings; a bottomplate mounted in the casing; a spindlesecured to the bottom plate; abolt-carrying lever pivotally mounted on the spindle; a pivoted boltcarried by the lever and having a nose arranged to engage one ofthenotches of the shackle; aspring tending to yieldingly hold the boltin engagement with the shackle; a dog having an arm bearing against aprojection on the lever; tumblers controlling the position of the(ll:g;:1l'lll means for actuating the tumblers.

4. The combination of a casing; a notched shackle; a shackle casinglocated within the lock casing and adapted to receive one leg of theshackle, said shackle casing being slotted; a stop located in the slotand extending into the path of. the shackle; and a spring tending tohold the stop in position,

said stop being arranged to engage the shackle;

5. The combination in a lock, of a casing; a spindle in the casing; abolt-carrying lever pivotally mounted on the spindl and having aprojecting stop; a stop-pin on the casing to limit the movement of thelever in one direction,- a bolt pivotally mountnd on one end of thelever and having a beveled nos-c, said bolt arranged to engage the stopon the lever; a spring tending to yieldinglyhold the bolt against thestop; a dog havingan arm; a projecticm on the lever located in the pathof the arm; notched tumblers on the spindle arranged to be moved intoand out of position; means for movingthe tumblers; and anotched shackleextending into the lock casing and arranged to becngaged by the nose ofthe bolt.
